Thomas Korte and Carine Magescas, founding partners at AngelPad, ask the startups they admit to remain in stealth mode as long as reasonably possible. They also require AngelPad participants not to attempt to raise outside seed capital or venture funding until after they complete the 10-to-12 week bootcamp.

The companies get a minimum of a $50,000 seed investment from AngelPad.

Instead of developing investor relationships throughout their program, AngelPad asks entrepreneurs to focus on winning customers, attaining user feedback, and honing their technology and business models accordingly.

According to Magescas, the accelerator saw thousands of applications this year, among them dozens from food, dating and travel app makers, but none of those were distinct enough to make the cut.

AngelPad’s recent cohort.

“We could make exceptions for strong teams and products, but generally like companies that work on solving problems you encounter in a professional setting,” notes Korte.

Wednesday marks the end of AngelPad’s sixth session in three years. Including this group, it has graduated 74 companies.

Among its alumni companies are the newly seed-funded Piggybackr and PICT, as well as Astrid (Todoroo), recently acquired by Yahoo. The following companies join their ranks:

DroneDeploy – Founder Mike Winn created Drone Deploy’s software as a service to manage fleets of drones in nonmilitary, commercial applications. He anticipates demand in agriculture, where drones can be used for monitoring fields, irrigation and crop dusting; health, where drones can drop supplies to people in remote locations who need them; media and entertainment, where drones can be used to do aerial photography.

Boxbee – This startup puts a twist on the traditional storage business. Customers use the Boxbee app to order boxes, and have them picked up and brought to a nearby storage facility. On request, Boxbee drops them back off–within 24 hours. Boxbee’s app lets users upload pictures of their boxes and contents, tagging them (like a Facebook photo) to keep track of individual items. The company cutely bills itself as a “stuff management platform,” or “Uber for storage.”

PogoSeat – This already revenue-generating startup helps sports teams and stadiums get more revenue, and higher “ticketholder” satisfaction per event, says founder Evan Owens. Their app offers seat upgrades during a game, concert or other event. The teams and venue operators connect with their customers through PogoSeat, and ultimately control the pricing of seat upgrades. They give some away for free, Owens noted. Existing clients include the Golden State Warriors and seven others. Across its client base, PogoSeat is averaging $2,000 worth of seat-upgrade sales per game.

Fieldwire Labs – The Fieldwire app helps workers troubleshoot problems at any facility where they work. It lets them upload a floor plan (in PDF format) of a hospital, factory, construction site or other location, and tag “issues” to a point on the map, attaching notes, a photograph, and highlights drawn on top of that image. The company hopes to do for people who manage physical environments what tools like PivotalTracker did for teams managing technical projects, says founder and Chief Executive Yves Frinault. They are already working with a number of pilot customers, including utilities and a solar manufacturer, Solaria.

SensorTower (incorporated as App Store Rankings) – This company helps mobile developers optimize their apps for easy discovery in any app store, and in multiple languages. Co-founder Oliver Yeh says building this technology his team discovered that the most popular Bible apps in the Apple app store did not have the keywords “Jesus” or “God” attached to them. SensorTower helped another Bible-related app maker use these keywords to gain visibility and users.

The remaining graduates in AngelPad’s latest cohort include a social music data service, Audience.fm; the content marketing network Chasm.io; HumanAPI, a platform that helps programmers use health data generated by wearable tech; enterprise, e-mail marketing tech firm, Iterable; a voice-controlled CRM platform, Roobiq; a service to help brands work with influential fashion bloggers, The Shelf; and a service that brings enterprise-grade phone features to smartphones, TrulyWireless.
